Edge scraping tool

Abstract

A tool for scraping an edge of a flat article, the tool comprising a first flat surface defining a first plane, a second flat surface defining a second plane at right angles to the first plane, and a cutting blade mounted at or near one end of the second flat surface, the plane of the blade being perpendicular to both the first plane and the second plane.

What is claimed is: 
     
       1. A tool for scraping an edge of a flat article, said tool comprising a first flat surface defining a first plane, a second flat surface defining a second plane at right angles to said first plane, said second flat surface adapted to glide along said edge of said flat article, and a cutting blade mounted at or near at least one end of said second flat surface, said cutting blade having a cutting edge parallel to and slightly above said second plane and perpendicular to said first plane, the plane of said blade being perpendicular to both said first plane and said second plane. 
     
     
       2. The tool of claim 1, wherein said cutting blade has an elongated hole for adjustably mounting. 
     
     
       3. The tool of claim 1, having a chip clearance relief notch between the cutting edge of said blade and said second flat surface adapted to permit flow of shavings produced from scraping away from said blade and said second flat surface. 
     
     
       4. The tool of claim 1, further including a relief notch at the juncture of said first and second flat surfaces. 
     
     
       5. The tool of claim 1, adapted in size and shape to be used by a human hand. 
     
     
       6. The tool of claim 1, having a replaceable cutting blade. 
     
     
       7. The tool of claim 1, having alternative cutting blade mounting positions at or near both ends of said second flat surface. 
     
     
       8. The tool of claim 1, wherein the cutting blade has an elongated hole for adjustably mounting, the tool has a chip clearing relief notch between the cutting edge of said blade and said flat surface adapted to permit flow of shavings produced from scraping away from said blade and said second flat surface, the tool further includes a relief notch at the juncture of said first and second flat surfaces, the tool being adapted in shape to be used by a human hand, the tool having a replaceable cutting blade and two alternative cutting blade mounting positions at or near both ends of the second flat surface, further including means for maintaining the edge of the cutting blade perpendicular to the first plane and slightly above the second plane.
